Hey ndrwgn, thanks for replying!
You're right, the screenshot doesn't show the issue. I didn't check the image before posting it and now I see it shows a normal screen, which is not how it looks in reality. Here's another screenshot, and apologies for the crappy picture but this is the only way I can show how the screen truly looks:
As you can see, the scroll bar is stuck a little bit to the right of its original position on the screen. This is what I ment by the screen being "shifted right". I've been doing some research and it seems that this isn't an uncommon problem with ubuntu users, at it's most likely related to the display drivers. I'll keep reading and I'll post the solution if I manage to fix the issue.
